'Expiation' in the Bible

And thus shalt thou do unto them, to cleanse them: sprinkle the water of expiation upon them, and let them cause a razor to pass over all their flesh, and let them wash their clothes, and cleanse themselves.

So you shall not pollute the land in which you are; for blood pollutes the land and no expiation can be made for the land for the blood that is shed on it, except by the blood of him who shed it.

Rejoice, O ye nations, with his people: For he will avenge the blood of his servants, And will render vengeance to his adversaries, And will make expiation for his land, for his people.

Seventy weeks are apportioned out upon thy people and upon thy holy city, to close the transgression, and to make an end of sins, and to make expiation for iniquity, and to bring in the righteousness of the ages, and to seal the vision and prophet, and to anoint the holy of holies.
